Referencing KiwiME's question from a bit back ... I'm not aware of seatbelt
rattling, but maybe a different position than where I have it lets things flop
around. I did attack the B-pillar anyway, at a first exploratory level, and
found it fairly easy to pop out the lower trim piece. Perhaps a pic showing
where the pop-pins are located will help others...
The key is that you have to pull back the door weatherstripping first, along
enough length to free the panel edges. It just friction-clips over the edge of
the welded seam, fortunately no glue. The strip has a stiffening element
inside, probably some sort of malleable metal, so you don't want to put a
kink in that or it'll be difficult to keep smooth when replaced. Pull enough so
the strip can lay aside without getting too distorted. A flashlight in through
the edge gap helps locate exactly where the pins are.
The seatbelt passes *through* the panel piece, so obviously it has to come
along for the displacement ride. I did not go after the upper panel because
I had to button this back up and go somewhere, but I imagine that digging
further in would be relatively straightforward. The lower panel has to be
popped loose and displaced before the upper panel can come off; that's how
they interlace.
